Copper(II) oxide or cupric oxide is an inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or copper(I) oxide (cuprous oxide). As a mineral, it is known as tenorite, or sometimes black copper.
As the name suggests, Copper (II) Oxide consists of one copper atom (Cu) and one oxygen atom (O). The ‘II’ in its name signifies that the copper ion in this compound has a +2 oxidation state. This is a result of copper losing two of its electrons to oxygen, which is more electronegative.
Reaction with copper oxide – Carbon monoxide reacts with copper oxide and forms copper and carbon dioxide. The reaction is given below – CuO + CO 🡪 Cu + CO 2

Close. It is produced on a large scale by pyrometallurgy, as one stage in extracting copper from its ores. The ores are treated with an aqueous mixture of ammonium carbonate, ammonia, and oxygen to ultimately give copper (II) ammine complex carbonates, such as [Cu (NH3)4]CO3.
18 Νοε 2023 · It is formed by oxidation of copper metal either with a chemical oxidizer, by heating in atmospheric oxygen or by electrochemical oxidation using copper as a anode. cupric oxide can be converted back to copper metal by carbothermal reduction, in which it is reduced by carbon under strong heat. Chemical.
